A is the correct choice.

This is based on the vertical line test. If you were to draw an imaginary vertical line on the graph, it would only intersect the graph at one point, which proves that all x values are different (a function).

9 1/2 divided by 3 7/10

OleMash [197]

Solution:

<u>Convert the fractions into improper fractions and solve.</u>

9 1/2 ÷ 3 7/10
=> 19/2 ÷ 37/10
=> 19/2 x 10/37
=> 19 x 5/37
=> 95/37

<u>Convert the fraction into mixed fraction (Not required):</u>

=> 95/37 = 37/37 + 37/37 + 21/37
=> 1 + 1 + 21/37
=> 2 + 21/37
=> 2 21/37

The solution to the problem is 2 21/37.

$\huge\text{Hey there!}$

$\huge\textbf{Question reads....}$

$\large\text{Which expression is equivalent to 2(x - 1) + x?}$

$\huge\textbf{Step by step to find your result}$

$\large\textbf{First you have to DISTRIBUTE 2 WITHIN the}\\\large\textbf{PARENTHESES}$

$\large\text{2(x - 1) + x}\\\rightarrow\large\text{2(x) + 2(-1) + x}\\\rightarrow\large\text{2x - 2 + x}\\\rightarrow\large\text{2x - 2 + 1x}\\\rightarrow\large\textbf{COMBINE the LIKE TERMS}\leftarrow\\\rightarrow\large\text{(2x + 1x) - (2)}\\\rightarrow\large\text{3x - 2}$
